Embodiment 1

[0032] This embodiment provides an interface structure of a rapidly replaceable end tool for a robot, including a robot end interface and a tool end interface.

[0033] Such as figure 1 As shown, the robot end interface includes a driving device, a transmission device, a first locking mechanism, and a first electrical interface.

[0034] Such as figure 2 As shown, the tool end interface includes a second locking mechanism and a second electrical interface.

[0035] The driving device can drive the first locking mechanism through the transmission device, so that the first locking mechanism and the second locking mechanism form a mechanical lock first, and then the first electrical interface and the second locking mechanism The second electrical interface forms an electrical connection.

[0036] In a preferred embodiment, the driving device includes a driving motor; the transmission device includes a trapezoidal screw, and the trapezoidal screw has a self-locking function. ...

Embodiment 2

[0050] This embodiment provides a dual-arm robot, including a dual-arm with an end and an end tool, and the end of the double arm can be docked with the end tool, and there is a device according to any one of Embodiment 1 of the present invention between the end and the end tool. The robot can quickly replace the interface structure of the end tool.

[0051] Compared with the prior art, it can be seen that the existing interfaces are all driven by discrete driving devices, and the system is complicated, resulting in large volume, heavy weight and low reliability of the interface, which cannot meet the requirements of robot astronauts. The invention only uses one motor to complete the mechanical and electrical connection, avoids completing the electrical connection in an unlocked state by separating the guide surface, and increases the reliability of the device.

Abstract

The invention provides a robot interface structure capable of rapidly changing an end-effecter. The robot interface structure comprises a robot tail end interface and an effecter end interface, wherein the robot tail end interface comprises a driving device, a transmission device, a first locking mechanism and a first electrical interface; the effecter end interface comprises a second locking mechanism and a second electrical interface; the driving device can drive the first locking mechanism through the transmission device, so that at first, the first locking mechanism and the second lockingmechanism form mechanical locking, and then, the first electrical interface and the second electrical interface form electrical connection. The robot interface structure does not need a complicated hardware control system, only needs a motor to finish mechanical locking and electrical connection, ensures light weight and high reliability, and also can meet the requirement that an astronaut robot can rapidly and reliably change a corresponding end-effecter within a short period of time.

Description

technical field [0001] The invention relates to a rapidly replaceable terminal tool interface for a robot, which belongs to the technical field of robots. Background technique [0002] In dangerous and complicated working environments such as armed police, public security, anti-terrorism and anti-riot, battlefield operations, harmful gases and nuclear radiation, the limitations of human beings will cause them to face dangerous scenarios. Therefore, robots can greatly compensate for the human body's own limitations by completing certain tasks instead of humans. We can take advantage of the disadvantages of robots and give full play to the advantages of robots to prevent human beings from being injured when working in dangerous environments. It can also reduce costs and improve work efficiency. However, it is difficult for existing robot end effectors to completely replace human five-fingered hands to perform various tasks, and it is difficult to perform complex operations onl...
